ABCO Tool & Die, Inc. is a mold manufacturer specializing in the manufacturing of plastic injection molds for molded
optical parts. The purpose of this presentation is to explain the concepts and procedures required to build a mold that
produces precision optical parts. Optical molds can produce a variety of molded parts ranging from safety eyewear to
sophisticated military lens parts, which must meet precise optical specifications. The manufacturing of these molds
begins with the design engineering of precision optical components. The mold design and the related optical inserts are
determined based upon the specific optical criteria and optical surface geometry. The mold manufacturing techniques
will be based upon the optical surface geometry requirements and specific details. Manufacturing processes used will be
specific to prescribed geometrical surface requirements of the molded part. The combined efforts result in a robust
optical mold which can produce molded parts that meet the most precise optical specifications.
